Zhou Jianping: The accuracy of the Chinese Sky Survey Telescope is comparable to that of Hubble, but the field of view can reach 300 times that of Hubble

IT House September 1 news, today, at the opening ceremony of the 2022 World Artificial Intelligence Conference, Zhou Jianping, chief designer of China's manned space project and academician of the Chinese Academy of Engineering, said that China may launch a sky survey telescope next year, which can detect dark matter in the universe. The accuracy is comparable to that of the Hubble telescope, and the field of view is 300 times that of Hubble. IT House learned that the China Manned Space Engineering Office previously stated that my country plans to launch China's first large-scale space survey telescope next year to carry out wide-area survey observations, which will focus on the formation and evolution of cosmic structures, dark matter and dark energy, and exoplanets Carrying out cutting-edge scientific research on solar system celestial bodies and other aspects is expected to achieve a number of major innovations. At present, new progress has been made in the development of the first prototype of the sky survey optical facility. The telescope is expected to launch after the completion of the Chinese space station. As the optical module of the Chinese space station, the Sky Survey Space Telescope will be equipped with an optical system with a diameter of 2 meters and a series of state-of-the-art detectors. The size of the telescope is equivalent to a bus, standing three stories high and weighing more than ten tons. The sky survey space telescope is mainly divided into two parts, including the sky survey optical facility and the sky survey platform. In the application and development stage of the space station, the scientific experiment cabinets arranged in the space station cabin and the large-scale load facilities outside the cabin will also be used to carry out larger-scale space research experiments and new technology experiments. It mainly involves many fields such as space life science and human body research, microgravity physics science, space astronomy and earth science, and new aerospace technology. IT House learned that the research facility of the Sky Survey Space Telescope will co-orbit with the space station, and conduct wide-area sky survey observations, and will carry out cutting-edge scientific research in the formation and evolution of cosmic structures, dark matter and dark energy, exoplanets and solar system celestial bodies, etc. . According to China's manned spaceflight project plan, the Sky Survey Space Telescope is expected to be put into scientific operation around 2024. The planned mission life is 10 years, and the life can be continuously extended through maintenance. According to reports, my country's Sky Survey Telescope is similar to the Hubble Telescope in the United States, but many performance indicators are higher than the 32-year-old Hubble Telescope. The imaging quality and resolution of the survey telescope are comparable to those of the Hubble, but the field of view of the survey telescope is more than 300 times larger than that of the Hubble, because the performance of the primary mirror detector determines the performance of the telescope. In addition to the main mirror, the survey telescope is also equipped with some back-end modules, including coronagraph, terahertz, multi-channel imager, etc., through the joint work of these modules to achieve scientific goals. The optical facilities of the survey telescope are installed on an optical module platform, and the optical module platform and my country's space station co-orbit flight. The sky survey telescope can not only achieve wide-area sky surveys, but also perform extremely deep observations for specific targets, and can achieve extremely deep imaging observations of 400 square degrees. Zhang Wei, a researcher at the Center for Space Application Engineering and Technology of the Chinese Academy of Sciences, said that the performance indicators of the survey telescope are better than those of international advanced telescopes such as the Euclidean telescope and the Hubble telescope. "China's first large space survey telescope is planned to be launched next year, and will carry out cutting-edge scientific research in many aspects" "The Chinese version of "Hubble" is coming: the space station survey telescope is planned to be launched in 2024"
